Full List of Core i7 (LGA 1366) Compatible Heatsinks

[bluetooth]

Thermalright - all Ultra series, HR-01 Plus, HR-01 4U, HR-01 3U and Ultima 90.
Noctua - All coolers. Free upgrades to LGA1366 brackets for current Noctua heatsink owners.
Scythe - All coolers. Brackets will be sold separately and parts supporting LGA1366 will be given a 'Rev. B' addition to the name. The new Mugen 2 will suport LGA1366 from the get go
Thermaltake - V1 and Big Typhoon VX will be updated with LGA1366 support. All Thermaltake water cooling ('LCS') will be updated for LGA1366 support. No confirmation of being able to buy the brackets separately but the new brackets have been given individual part numbers (A100069 for V1 and A100070 for Big Typhoon VX) so I would presume they will be made available separately.
Coolermaster - The V8 will have LGA1366 compatibility (should be in Aus @ Rectron in the next container due in about four weeks) and the Aquagate Max is being updated for LGA1366 with a likely revamp of the water block used - details were sketchy but it was mentioned it needs the block needs to be redesigned.
ASUS - Triton 81 cooler.
Nexus - FLC-3000 cooler.
